Error/Warning: cloud.TuyaOpenAPI: Request failed - no token received

I have used OH3 and Tuya Cloud Project to connect to my Tuya devices.
Since a few days I get the error message every minute:

2023-12-24 11:04:31.421 [WARN ] [] - Request failed: Result{timestamp=1703412645871, code=1013, msg=request time is invalid, success=false, result=null}, no token received

I have found out that it may be due to an expired test period in the Tuya Cloud developer environment.
Unfortunately, I can no longer find the tutorial for setting it up in Tuya.
Can anyone tell me what I need to set up there and subscribe to if necessary?
What does it cost? Does anyone use it?
Perhaps someone also has the link to the instructions on how to obtain the required data (Access ID, Access Secret, Device IDs, Device Local Key, Product ID)?
Thanks in advance.

I don’t know how to enter it either, can anyone help? What should I enter?
